Do all radio waves travel at the same speed? I will look into it, just asking if you know beforehand.
Yes, all radio waves, in fact all waves within the electro-magnetic spectrum, move at the same speed. What changes is the frequency, or length of the wave. a longer wave, will have a lower frequency, meaning it occurs less often within a given time frame.
Wait a minute. You're saying ALL radio waves move at the same speed but low frequency waves occur less often than high waves. What does that mean?
The radio signal you receive on the low end of the AM Broadcast Band on your radio - 550 Kilohertz for example - will take the same length of time to get from the transmitter at the broadcast station to your radio receiver as the radio signal on the FM Broadcast Band at 105 Megahertz .
The speed of radio waves is the same no matter what frequency.
Just like sound waves. On a symphony orchestra you will hear the low frequency notes of the Bass Horn as at the same time as the high frequency notes of the Flute if they are playing in time.
RADAR works on the same principle and they work on different frequencies but give the same results no matter what is their operating frequency.
